The first Wide Cab EMD made. While the GMD SD40-2W technically was the first, this design is seen on EMD SD60Ms, EMD SD60Is, EMD SD70Ms and so forth. This cab design is now replaced by the EMD Wide Cab 2.

The EMD SD (special duty) series are a strong and reliable kind of locomotive which still serve America's rails today. They have proved themselves reliable by clocking in several million miles of freight service.
